A printer 110 to which an ink tank 11 for containing ink IK is fixed and configured such that a user can supply the ink IK to the ink tank 11 includes a sensor 60 for performing remaining ink detection for checking whether or not the ink IK is present at a predetermined position in the ink tank 11, a control unit 40 that executes the remaining ink detection using the sensor 60, a consumption calculation unit 42 that calculates consumption of the ink IK that is consumed from the ink tank 11, and a storage unit 50 that updates and stores the consumption of the ink IK calculated by the consumption calculation unit 42. When a print job is being executed, the control unit 40 executes the remaining ink detection after a first predetermined amount of the ink IK is consumed.
